I have used an Olympus VN-5000 without any problems. However, the VN-5000 
does not have a way to directly download to a computer. I now use a RCA 
model VR5220 (I think I got it at Wally World). There are no RF issues. I 
connect it directy to the speaker out jack on my radio. It timestamps the 
files and has USB connection for saving .WAV files directly to a computer. I 
love it!
